2 Claims.

My invention pertains in general to package constructions andspecifically relates to a form of` package having leaved article bearingmembers.

One of the objects of my invention consists in providing a packageconstruction having a plurality of leaves formed to enclose articles inspaced relationship.

Another object of my invention comprises providing a leaved packageconstruction having a plurality of sheets of coated viscose materialjoined in leaved bond by an embrittling heat crimping process.

A further object consists in producing a commodity package having amultiplicity of articles individually enclosed in spaced relationship insuperimposed sheets.

A further object resides in the provision of a closure arrangement for aleaved package structure in which cover sheets are provided withoppositely closed ends enclosing commoditycontaining package sheets.

These and other objects will be apparent from the following, referencebeing had to the accompanying drawings in which like reference numeralsindicate corresponding parts and in which:

Fig. 1 is a top plan view of a preferred embodiment of the leavedpackage construction of my invention;

Fig. 2 is a sectional view taken along the line 2--2 of Fig. l;

Fig. 3 is a top plan view of another form of the package construction ofmy invention;

Fig. 4 is a side view of the representation of Fig. 3;

Fig. 5 is a View showing the structure of Figs. 1 and 2 in a differentform provided with a closure arrangement;

Fig. 6 is a transverse sectional view of the representation of Fig. 5taken along the line 5 6;

Fig. 7 is a view of another form of the package with a closurearrangement; and

Fig. 8 is a side view of the representation of Fig. '7.

My invention is directed to providing a form of package in which aplurality of individual articles can be maintained in individuallysealed and spaced relationship in a manner suchithat each article may beused individually as required. Such a package has a great many differentuses. For example, in the dispensing of pharmaceutical commodities, aplurality of pills can be individually sealed in the package of myinvention 1935, Serial No. 23,362

(Cl. 20G-56) together with a sheet of linstructions as to the properdosage. In this use, the individual doses can be used as requiredwithout disturbing the sealed protection of the other pills or doses andwithout disturbing or destroying the dosage instruction sheet. This formof package has many advantages over the usual method of packaging suchpharmaceutical commodities in boxes and bottles, since the package of myinvention is,

from the manufacturing standpoint, of inexpenl0 sive construction andadapted to high speed fabrication, and is, from the consumersstandpoint, superior to boxes and bottles since the packaged articlesare maintained in sealed and sanitary segregation adapted for individualuse. The annoyance attendant the opening and closing of bottles andboxes is also eliminated.

In accordance with the invention, the commodity articles are provided inspaced relationship between sealed layers of transparent regeneratedcellulose. These sheets of cellulose material are sealed together inbook formation with front and back cover sheets. The cover sheets arepreferably provided with indicia such as advertising and instructions asto the use of the packaged commodity. For example, when the packagedcommodity comprises pharmaceutical pills and the like, the indicia mayinclude instructions as to the dosage of such pills. According totheinvention, these front and back cover sheets may be joined along theirouter vextremities in a closure arrangement. This closure arrangementenables the package to be maintained in a closed condition prior toactual use. That is, the commodity-containing sheets are not exposed tohandling or misuse until the package as a whole is ready for use. Whenthe package is ready for use, the closure may he opened by the consumerto permit access to the leaved formation of the package structure.

Referring to the drawings in detail, and particularly to Figs. 1 and 2,there are provided a plu- 'rality of sheets of flexible viscose materialI, 2, 3, and 4. The material of these sheets is of what is commerciallyknown as cellophane having a heat treatment coating thereon, althoughother suitable materials may be' used. The sheets I and 2 together forma multiple article-enclosing package unit. In accordance with theprinciples of my invention there may be any number of such packageunits, but for purposes of simplicity I will limit my present disclosureto two such units.

One of these package units will now be considered in more detail. 'I'hesheets 3 and 4 are divided into a multiplicity of adjacent squares by acrimping process which forces the two sheets 3 and 4 together into aninterdigitated bond. This forced crimping is done under heat conditionsso that the structure of the coated viscose material is changed tobecome embrittled in the crimped portions, thus forming a very tightlysealed bond and also being more easily susceptible to tearing by theconsumer to allow the packaged article to be easily removed.

Referring to Fig. 1 it will be noted that the squares are separated bythe vertical areas a and b, and the narrow horizontal area c, in whichno crimping occurs. 'I'hese areas form separation lines for the squaresand also serve as guide lines for guiding and tearing of the embrittledstructure in removing a square by the consumer. Other horizontal lines,such as represented by the area d are also without crimping and leadinto the article-containing recess "E between the sheets 3 and 4. Theselines represented by d are also tearing guide lines which guide thetearing of the embrittled portions into the package containing recess E.It will be seen that in the center of each of the crimped squares therecess E is provided in circular formation within which the packagecommodity is placed. For example, a round pill 6 may be placed withinthe recess E as shown, although several such pills or other forms ofarticles for individual use can be placed therein.

Between the squares are perforated portions 8, II, and I2 as shown.These perforated portions are cuts extending through the two sheets 3and 4 and form starting points for tearing each of the individualsquares. In other forms of my invention I may also provide theseperforated starting portions at the beginning of the guide linesrepresented at d and in still another form I may omit the guide areascl" altogether. It will be understood that the package-unit formingsheets I and 2 are similar to the package-unit forming sheets 3 and 4.

Underneath the unit comprising sheets I and 2 there is provided a sheet9, while above the unit comprising sheets 3 and 4 there is provided asheet I0. Sheets 9 and I0 are preferably formed of material similar tothat of which the sheets I4 are composed and serve as top and bottomcovers and indicia sheets; Upon these sheets 9 and III various lindiciamay be' placed. On the front sheet the name ofthe manufacturer andvarious advertising may be provided, while on the bottom sheet 9instructions for use 'of the packaged commodity maybe placed. Thisarrangement can be varied, of course, at will, the

sheets 9 and I0 serving as indicia cover sheets in general for anydesired purpose..

The uppermost, portions of the sheets' I-4 and the sheets 9 and I D arejoined together for an area F which is processed to form a crimped bondsimilar to the crimping surrounding the recesses E. 'Ihis bond area F isembrittled and due to the thickness ofthe several sheets forms a bindingarea or backing for the leaved or book construction of the package as awhole.

In use, the consumer may selectively remove the packaged commodity fromeach square for individual use in accordance with instructions on theindicia cover sheets. Although Vthese individual squares may be torn outfor individual use from time to time, the area F is still maintainedintact to support the indicia cover sheets and maintain the identity andform of the package.

Fig. 3 represents another form of the leaved package construction of myinvention. This construction is similar to the construction of Figs. 1and 2 except that the unit comprising the sheets I and 2 is staggeredwith respect to the unit comprising the sheets 3 and 4. 'Ihis staggeringis arranged so that the packaged commodity carried by sheets l and- 2 ispositioned in the spaces between the packaged commodity carried by thesheets 3 and 4, thus effecting a spatial arrangement in which thepackaged articles are arranged in rows in echelon. This spatialarrangement makes it possible to more compactly close the separatepackage units since the recesses E are staggered with respect to eachother and therefore do not abut one above the other. Fig. 4 shows howthe package units comprising the sheets I and 2 and the sheets 3 and 4,respectively, can be positioned very closely when the package as a Wholeis closed.

In this arrangement shown in Figs. 3 and 4 there are provided sheets 9aand Illa which are cover indicia sheets similar to the sheets 9 and I0.However, the sheets 9a and I 0a are of a width represented by A in' Fig.3, while the sheets I and 2 are of a width represented by B, and thesheets 3 and 4 are of a width represented by C". It will be seen thatthe staggered spacing of the package units is equivalent to the spacingbetween the packaged articles in each respective unit, the cover indiciasheets being wider than either of the package units. The exact relationship of the staggered arrangement is quite apparent from therepresentation of Fig. 3. In other respects, the package of Fig'. 3 issimilar to the package of Fig. l.

Figs. 5 and 6 represent a structure substantially similar to thatdepicted in Figs. 1 and 2, except that, in this instance, cover sheets9b and Ib are integrally contiguous and provided with a central row ofperforations I5. It will be noted that the package sheets I and 2 extendinto the notch provided by the closure of the sheets9b and IIIb and areheld thereby. In this arrangement the commodity-containing sheets I and2 are not exposed to handling or misuse until the package as a wholeisready for use. When the consumer desires to begin the use of the package-in removing individual articles, he may open the booklet by severingalong the perforations I5, thereby exposing the package-containing leafbetween the cover sheets.

The structure shown in Figs. 7 land 8 is similar to that shown in Figs.3 and 4 except that the cover sheets 9c and Inc are provided withextending portions at the lower side of the package. Similarly, thesheets I4-4 are also provided with -a lower extending portion. 'I'heselower extending portions are all bonded together under a heat andcrimping treatment to provide a bondingarea G similar to bonding area F,A weakened separation line I1 is provided extending across the packageimmediately above the area G and notches I6 are provided in this area topermit easy separation of the area G from the rest of the package. Thearea G forms an embrittled inseparable oxidized bond. When the consumerwishes to use the package he may grasp thearea G with his fingers andremove the same by tearing from the notches I6 along a separation lineI'I. The package is then in open booklet form with the individualpackage leaves exposed for use in separation of the individual commodityunits. It will be understood of course that the booklet cover sheetsshown in Figs. 5-8 may be of various materials aooasea including coatedregenerated cellulose and can be provided with indicia in the form ofinstructions and advertising material similar to the corresponding coversheets described in connection lwith Figs. 1 4. The closure feature notonly avoids unnecessary exposure and mishandllng of the booklet packagesheets before they are in active use, but maintains them in the properstructural position to avoid bending and separation of the leavedstructure.

The cover sheets 9b and lllb as well as the cover sheets 9c and |00 canalso be sealed along the right hand and left hand edges as shown inFigs. 5-8 so as to form completely enclosing envelopes. These seals mayalso be provided with perforations and weakened areas so that thepackage will be in book form when these seals are broken.

It will now be apparent that I have provided a novel form of leavedpackage which offers great utility and convenience in its use. Theespecial advantages reside particularly in that a great manyindividually packaged articles can be maintained in a readily accessibleyet sealed and sanitary segregated formation with printed in- Ystructions or advertising matter in constant association to form aunitary and compact package. Although I have shown modifications andstructural details it will be readily apparent that my packageconstruction can be modified or changed by those skilled in the artwithout departing from the intended scope of my invention. I de nottherefore desire to limit myself to the foregoing except as may bepointed out in lthe appended claims.
